spool move/rename question
by Dave McGuire 09 Oct '23

09 Oct '23

Hi folks. Our mail server's spools are structured like this: /var/mail/<domain>/<user> We have an existing user with a lot of mail that we need to move from one domain to another. Our mail system is database-backed so changing the account is trivial, but can I just move the <user> directory from the structure above from one <domain> directory to another and expect everything to be ok? Or is there a better approach? (of course I'll do a backup first) Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA

qp and Invalid quoted-printable input trailer: '=' not followed by two hex digits
by Arkadiusz Miśkiewicz 09 Oct '23

09 Oct '23

I have a mail (attached) for which dovecot reports: imap(test): pid=<32688> session=<UOVJ/0UHlM3B7y+g>, Error: Mailbox INBOX.test: UID=1: read(<binary stream of mailbox INBOX.test UID 1>) failed: read(/var/mail/test/.test/cur/1695887652.M710714P17846.mbox13:2,RS) failed: Invalid quoted-printable input trailer: '=' not followed by two hex digits and I fail to see why. There is = used at the end of lines as soft-line break. Also if you delete "przez system Spa=" it works. If you lave it and delete " =" line it also works. Doesn't seem to be consistent. Is dovecot too restrictive here? dovecot 2.3.20 and 2.3.21 -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

bug report: lmtp fails on root-squashed NFS filesystem
by Anne Bennett 09 Oct '23

09 Oct '23

Hi, all. I'm trying to set up Postfix with dovecot LTMP delivery on a host where the user files (/var/spool/mail as well as home directories) are on NFS filesystems, which are exported root-squashed to the mail server. I definitely don't want to give the mail server root permissions on the user files. LMTP delivery fails with this logged message (e.g.): Nov 16 17:51:36 lust dovecot: lmtp(anne)<16830><mkkzEPg1lGG+QQAAs/mAJw>: msgid=<202111162229.1AGMTfAO024765(a)vindemiatrix.encs.concordia.ca>: save failed to INBOX: Read-only mbox I found this posting where someone else had a similar problem and traced it in some detail back in 2019: https://dovecot.org/list/dovecot/2019-February/114611.html but apparently no one answered the fellow. In order to check that this is indeed the same problem, I temporarily changed the INBOX definition to make it write into /var/tmp/ (on a local filesystem), and delivery worked. I then temporarily changed the INBOX definition to make it write into an NFS filesystem with root NOT squashed, and again it worked (after I chmodded the directory to 1777 to allow any user to create a file). I believe that the person who wrote the above posting is correct: at some point, file access is (incorrectly) checked as root instead of as the target user. This is a bit of a showstopper for me. Any plans to address this? I attach the output of "dovecot -n", fwiw, but I don't think that this is a configuration problem...

Hi, I'm running dovecot 2.3.16 on Ubuntu 22.04.2. But when I start dovecot, I can only see that the services are failing to start. It don't show any additional error about why it's failing, may be because the log service is not running?
